PHIAL Filed Aug. ze, 1955v /N veA/fom Patented Nov. 16, 1937 UNITEDSTATES PATENT OFFICE Application August 26, 1936v Serial No. 98,100 InSwitzerland September 7, 1935 A phial is now made of a glass bulb whichis sealed in a flame and in which are kept medical preparations intendedto be inhaled, or solutions for injection, and which are thus keptaseptic.

A phial-tube is also known for which a special syringe is necessary. I h

Thephials which require a le for cutting them or breaking them presentdisadvantages such as untimely breakage, defective les, mssibility offorgetting the file, etc., and also present the danger of smallfragments of glass being accidentally introduced either for example inthe syringe, or even in the body of the patient.

The phial-tube further presents in addition te the disadvantage of aspecial syringe, the danger of having as a closing means a cap thecentre of which is provided with an orice through which the needlepasses and where in consequence bacteria, germs in the air and dust mustinevitably accumulate.

The present invention overcomes these disadvantages and presents aconsiderable technical improvement. It relates to an improved phialcomprising a metal non-perforated capsule characterized by the featurethat the said capsule comprises at least on thin 'part intended to bepierced by the needle of a syringe without dam aging the needle, thiscapsule covering a member of elastic material comprising at least oneorice, the said member being placed on a metal sheet closing the openingof the phial. 1

The accompanying drawing shows by Way of example two forms of embodimentof the device according to the invention.

Figure 1 is a view in axial section of a rst form of embodiment.

Figures 2 and 3 are plan views of two mem bers of elastic material.

Figure 4l is a view on a large scale of a metal cap. Y

Figure 5 is a view in axial section of a second form of embodiment.

Figure 6 is a plan view of second form oi embodiment.

Figure '7 is a view in axial section of the second form of embodiment,the closure of the phial being traversed by the nozzle of a syringe.

The phial shown in Figures l, 2, 3 and 4 comprises a relatively thickglass tube I provided Iwith a base; the other end of thetube I isprovidedl with an opening iiared in such a way as to form a circularshoulder. This opening is closed by means of a metal sheet 4 for exampleof tin, applied on the shoulder 3. n ,this sheet is placed a plate ofcompressible'material for example such as rubber,v which is itselfcovered by means of a metal cap t, for example of pressed aluminiumsecured around the end of the tube i. An orice l, eccentric or not, isprovided through the plate t; a thin part t is arranged in the centralpart of the cap it, this thin part as well as the orifice l and thesheet i being intended to be traversed by the needle of a syringe. Theorifice i may be replaced by a slot or by two slots 9 arranged in theform of a cross.

The wall of the tube i oi the container shown being relatively Ithick,will break only seldom during the various operations such asdlsinfecting, filling, closing, sterilizing, packing and transport towhich the phial is subjected. Before the phial is used, the caps 6 caneasily be sterilized either by means of a name or a disinfectant. Thecon- ,tents of the tube I can be aspirated by means of' a syringe, theneedle of which can easily perforate the metal cap t without beingblunted, the said metal cap t comprising for this purpose a very thinpart il.' The needle of the nozzle then passes iirstly through the plateof compressible material and secondly through the tin plate il. Thecontents of the phial can then be aspirated Without dimculty due to thepresence of the Oriiice l provided in the rubber plate which preventsthe formation of a vacuum in the phial astio which may be capable ofpreventing the discharge.

A fluid-tight seal of the phial illustrated is en sured due ,to theplate of compressible material, the phial. being thus of the kind termeduniversal type',

The phial shown in Figures 5, 6 and I comprises a closure provided witha metal non-perfo.1 rated capsule it, for example of aluminium, fas'ltened or crimped around a circular shoulder li provided with a tube i2;the said capsule It pro vided with a thin part It is secured on a memberIt, for example a rubber washer. 'Ihe capsule i@ comprises two incisionsI5 the depth of which is less than the thickness of the capsule, theseincisions being intended to facilitate the subsequent perforation of thecapsule It by the nozzle It of a hypodermic syringe It.

The member i3 which is placed on a tin sheet 2i closing the opening ofthe phial comprises iirstly an orifice 20 opposite the thin part I4intended for the passage of the nozzle I6, and secondly an orice il forthe aspiration of the solution contained in the phial I2 when thecontents are discharged by means of a syringe I8. The oriiice I1 oi' thevmember I3 is covered with a ster- Y ilized filter it.

The closure of the phial shown permits the solution contained in a phialI2 to be aspirated by means oi' a syringe I8, the nozzle I6 of which ispreviously cleaned and sterilized for its passage ,through the oriiice20 without any danger oi pollution of the said solution. The solution issubsequently-injected by means of a needle arranged ior this use at theend of the nozzle IB.

It will be understood that the shape and volume of the phials may bevariable as desired.

Having now described myv invention, what I claim as new and desire tosecure by Letters Patent is:-

1. Phial for containing medicinal preparations comprising a metallicnon-perforated capsule,

said capsule Vcomprising at least one thin part lny tended to be piercedby the point of the needle o! a syringe without damaging the needle, thesaid capsule covering a member of elastic material provided with atleast two orifices, one of which is located opposite lthe thin part ofthe capsule and permits the penetration of the nozzle of a hypodermicsyringe for aspirating the contents of the phial, the other oricepreventing the formation of a vacuum in the phial and being proof ahypodermic syringe for tents of the phial, the other orifice preventingthevided with a sterilized lter, the said member of elastic materialbeing placed on at least one metallic sheet closing the opening of thephial.

2. Phial for containing medicinal preparations comprising a metallicnon-perforated capsule, said capsule comprising at least one thin partintended to be pierced by the point of the needle of a syringe withoutdamaging the needle, the said capsule covering a member of elasticmaterial provided with at least two orices, one of which is locatedopposite .the thin part of the capsule and permits the penetration ofthe nozzle aspirating the conformation of a vacuum inthe phial and beingprovided with a sterilized filter, the said member of elastic materialbeing placed on at least one metallic sheet closing the opening of thephial, the

capsule further comprising at least one incision ,the depth of which isless than the thickness oi the wall of the said capsule for facilitatingthe penetration of the nozzle of a syringe into the said phial. VITALMONNIER.
